Specs

R410A: 8-48HP, up to 144HP/R32: 8-22HP, up to 40HP/3Ph/380-415V/60Hz

Space-link technology

Free choice communication wiring sequence:
In addition to the traditional hand in hand connection, the communication wire supports four connection ways, star connection, ring connection and tree connection, which greatly reduces the installation limitations.
1192 Communication protocol.Compared with the ordinary communication protocol, the communication rate has been greatly improved, there will be no delay reaction.

Continuous system operation in case of partial unit power outage

Continuous system operation in case of partial unit power outage:
When an indoor unit is powered off, the VRF system can continue to run without reporting the fault and do not affect the operation of other indoor units. (less than 10 indoor units are allowed to lose power)

24V flexible communications

When the guest leaves the hotel room and remove the card to power off the MRV indoor unit, the EEV in the indoor unit may not be fully closed, thus the indoor unit evaporator freezes because of excess cooling capacity. The built-in multitenant site using separate circuit breaker for each indoor unit to close the EEV.

IP55 & rotatable electrical control box

IP55 grade protection ensures the stable operation of the electrical control system. the rotatable electric control box design make it easy to repair the components behind the electrical control box, only to loosen the screws on the right side of the control box to swing it out.
Black fin (optional).

VRA technology

Advanced VRA technology Automatic variable refrigerant adjustment according to ambient conditions, the cooling capacity or cooling load of the air conditioner is adjusted according to different outdoor temperatures. Advanced VRA technology adds correction to the evaporation temperature of the current mode to improve energy efficiency under the current modes.

High reliability

Direct refrigerant cooled PCB:
Refrigerant directly into the fin interior, the fin cooling compressor drive module, reduce a layer of heat resistance. Under the same operating condition, the temperature of the compressor drive module is lower than 8°C, to ensure that the whole unit can continue to work under the high temperature.

Super Convenience

Smart backup operation:
The compressors in the same unit serve as backups for each other. Even if one of the compressors breaks down, the unit can still operate. For the multi-module combination, in case of breakdown of one outdoor unit, the other modules can continue to operate. The backup operation time can reach up to 15 days.

Simple addressing IDU

Simple addressing IDU
Use automatic addressing mode to set IDU and ODU addresses. If the AC system is powered off, the original address wibe retained, solve the pain point of resettng the address after the power faiure.
Use the indoor unt PCB board dip set addressing.
Use wired controller set the indoor unit addressing.
